LNBP12A, LNB Supply and Control Voltage Regulator,13/18V Output

The LNBP12A is a high-performance monolithic voltage regulator designed to supply and control LNBs (Low Noise Block downconverters) in satellite receivers. Encased in a rugged Multiwatt-15 package, it offers dual LNB outputs with selectable 13V or 18V voltages, plus a 1V boost feature for cable length compensation. This device integrates a factory-trimmed 22kHz tone oscillator, enabling seamless DiSEqC™ signal encoding and fast start-up for reliable satellite communication.

With built-in protection features such as short-circuit protection, thermal shutdown, and backward current protection, the LNBP12A ensures safe and dependable operation. The bypass function allows it to work in master-slave configurations, enhancing flexibility in multi-receiver systems. Ideal for both analog and digital satellite receivers, the LNBP12A is the go-to choice for robust and efficient satellite communication solutions.
